Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a mounting structure for plate glass.

[Prior Art] A structural silicone construction method is known in which sheet glass is fixed and attached to an opening in a building using an adhesive such as silicone. As a safety measure for this construction method, the corners of the fixed plate glass were placed in a third position.
It is secured with corner fittings 1 as shown in the figure. However, as shown in FIG. 4, the conventional corner fittings pass through the joints of the sash frame 3 where the sheet glass 2 is bonded with the structural silicone 7, and the bolts 5 are tightly connected to the structure 4 on the indoor side. Therefore, even if the watertight gasket 6 is used to seal, the seal between the bolt and the gasket becomes a water leakage path. To prevent water leakage, fill the area around the bolt with sealant.
Earthquake resistance will be strained, leading to twisting of the metal fittings and breakage of the gasket, which will cause trouble to the entire mounting section.

[Problems to be solved by the invention] The purpose of this invention is to solve the above-mentioned drawbacks of the conventional mounting structure. This improves watertightness.

[Means for solving the problem] The present invention was made to solve the above-mentioned problem, and the periphery of the plate glass is glued to the sash frame fixed to the structure of the building, and the interior of the sash frame is bonded. is sealed with a watertight gasket so that rainwater is guided into the sash frame through the joints and discharged, and the corners of these sheet glasses are held and fixed from the outside with corner metal fittings. To provide a sheet glass mounting structure in which a corner metal fitting is inserted into the frame so as to be hooked on the edge of the sash frame, and the corner metal fitting is fixed to the sash frame by screwing the corner metal fitting to this metal fitting. .

[Example] Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partial sectional view similar to FIG. 3 of the glass plate mounting structure according to the present invention. As shown in the figure, the plate glass 2 is attached to the sash frame 3 attached to the structure 4.
At least its upper and lower peripheral portions are bonded with structural silicone 7. Corner metal fittings 1 are provided at the corners of these glass plates 2 at the joints of the sash, and are adapted to lock the glass plates 2 adhered to the sash frame 3 from the outside.

This locking is performed by attaching the corner metal fitting 8 having the bolt hole 11 as shown in FIG. 2 to the sash frame 3.
This can be accomplished by inserting the corner metal fitting into the inside of the corner metal fitting, locking this corner metal fitting holder to the edge 9 of the sash frame 3, and tightening the tightening bolt 5 of the corner fitting 1 to the corner metal fitting holder.

In this case, the inside of the sash frame 3 is sealed by a watertight gasket 6 attached to a rib 10 set up on the sash frame.

Furthermore, by making the depth width of the corner metal fitting holder 8 match the distance between the edge 9 and the rib 10 of the sash frame 3, the safety of the corner metal fitting holder 8 inside the sash frame is increased, and the installation of the corner metal fitting 1 is facilitated. becomes.

In the present invention, plate glass includes colored or surface-coated glass plates, crystalline glass plates, ceramic plates, and the like.

[Effects of the invention] As explained above, in the present invention, when tightening the corner part of a plate glass bonded to the sash frame with structural silicone from the outside using a corner metal fitting, the corner metal fitting receiver inserted inside the sash frame Since the tightening bolt of the corner fitting is tightened to this corner fitting receiver, there is no need to pass the tightening bolt through the joint of the sash frame and tighten it to the structure as in the conventional case. A watertight gasket provides a reliable seal inside the sash frame.

Furthermore, tightening of the corner metal fittings is extremely easy because the tightening bolts are simply screwed into the corner metal fitting receivers while the corner metal fittings are locked to the edge of the sash frame.

[Brief explanation of the drawing]

Fig. 1 is a partial cross section showing the mounting structure of the glass plate according to the present invention, Fig. 2 is a perspective view of the corner metal fitting holder, Fig. 3 is a front view when the corner portion of the glass plate is fixed with the corner metal fitting, and Fig. 4 The figure shows a sectional view taken along the line AA in FIG. 3 of a conventional plate glass mounting structure. In the figure, 1 is a corner metal fitting, 2 is a plate glass,
3 is the sash frame, 4 is the structure, 6 is the watertight gasket, and 7 is the structural silicone.

Claims (1)

[Scope of utility model registration request] The periphery of the plate glass is glued to a sash frame that is fixed to the building structure, and the inside of the sash frame is sealed with a watertight gasket so that rainwater is guided and discharged from the joints into the sash frame. In a mounting structure in which the corner part of the frame is held down and fixed from the outside by a corner metal fitting, a corner metal holder is inserted into the sash frame of the corner part so as to be hooked on the edge of the sash frame, and the corner metal fitting is screwed into this metal holder. A mounting structure for plate glass that is fixed to the sash frame by fastening.
